Mount rack frame

ABSTRACT

Mount rack frames for storing attaching vertically aligned devices are described herein. The preferred embodiment of a second mount rack frame comprises at least two laterally aligned modular rigid support structures along a rack base with mechanical fasteners that reversibly insert to adjust a dimension of a rigid multi-component support structure. Rigid modular support structures also align with and mechanically attach vertically to each other to increase storage space. Another embodiment of the second modular mount rack frame comprises a single rigid modular support structure that also can vertically align and attach another multi-component support structures without lateral alignment of these structures along a rack base. A third mount rack frame comprises two rigid vertical components, two rigid horizontal components and two rack base legs. None of the disclosed frames or other embodiments thereof require attachments to structures external to the frame to be free standing with or without attached stored devices, except for lowermost contact with a horizontal surface.

This application is a continuation in part of pending U.S. utility patent application Ser. No. 14/745,644 filed Jun. 22, 2015 which is a continuation of Ser. No. 13/387,029 filed Apr. 27, 2009, and which is a continuation in part of U.S. utility patent application Ser. No. 11/364,495 filed Feb. 28, 2006 and now abandoned.

BACKGROUND OF THE INVENTION

This invention relates to a second modular mount rack frame for storing computer related devices such as hubs, switches, routers and servers. More particularly this invention relates to a second modular mount rack frame with detachable rigid modular support structures. This second modular mount rack frame also contains connecting plates for vertical attachments, lateral adjustment components and vertically attachment of two individual modular rigid support structures. Furthermore, there are connecting brackets which attach to both mounted devices and modular rigid support structures, thereby effectively stacking them vertically within the frame.

The prior art discloses cabinets for storage of computer related device which are expensive and cumbersome. They also require humidity and temperature controls because of their non-ventilated interior environment. Prior art storage structures also lack flexibility for adjusting the horizontal dimension of the mount rack frame whenever devices deviate from standard horizontal dimensions. Furthermore, because these prior art storage structures are not modular; they cannot stack vertically upon each other in an interchangeable manner. Prior art storage structures also do not exhibit reversibly attached rack bases by which the mount rack frame moves across a flat horizontal surface such as a floor.

The second mount rack frame solves these problems in an economical manner and contains the advantages of the mount rack frame previously described in U.S. utility patent application Ser. No. 11/364,495. With partially elliptical apertures and appropriate mechanical fasteners, the horizontal dimension within a standard mount rack frame is easily manually adjustable. If mobility is desired, each mount rack frame reversibly attaches to a rack base which includes wheels or coasters.

The current mount rack frame comprises numerous prototypes with dimensions which conform to standardized measurements (as well as multiples thereof) of the computer device industry. Because the mount rack frame is modular, additional rigid modular support structures vertically stack upon posterior or first anterior rigid modular support structures for increased storage.

The second mount rack frame accommodates servers as well as hubs, switches, routers which were the subject of U.S. application Ser. No. 11/364,495. This improved second modular mount rack frame comprises larger wider frame components for easier assembly. Second mount rack frame also implements thick bolts with matching self-locking inserted hex nuts. As in the prototypes in U.S. application Ser. No. 11/364,495, now abandoned, modular rigid support structures stack upon each other vertically for additional storage.

My second mount rack frame has up to two sets of rigid vertically aligned components which are spaced to create up to two parallel rigid modular multi-component support structures with parallel horizontal rigid components. The anterior rigid modular multi-component support structure can be taller than the posterior modular unit or vice versa. In this second mount rack frame these rigid modular multi-component rigid support structures may also be the same height, although both attach to two corresponding straight base supports.

The second mount rack frame performs two important functions: It may connect at two opposing anterior points along a server or hub for support solely by two opposing vertical rigid support components. The second mount frame also connects at four points—two anterior and two posterior—along larger devices such as servers. The four point vertically second mount rack frame component can also be vertically expanded by adding interchangeable modular rigid support structures.

None of the prior art prototypes possess the capability for (i) reversible and interchangeable four opposing point and two opposing point support of computer related devices by (ii) the reversible removal of a posterior modular rigid support structure; and thereby (iii) reducing the mount rack frame to one anterior modular rigid support structure for lighter devices. The second mount rack frame comprises the structural capability to support

(i) more than one rigid multi-component support structure in vertical alignment and attachment to

(ii) both laterally aligned rigid multi-component support structures, and

(iii) with or without a maximum load of stored attaching vertically aligned devices.

In a second embodiment of the second mount rack frame a single modular rigid multi-component support structure comprises structural features, preferably aligned aperture pairs and inserted mechanical fasteners, by which to vertically attach another rigid modular rigid support structure. Each such vertically aligned modular rigid support structure is preferably interchangeable with the remaining vertically aligned modular rigid support structure. Each single modular rigid support structure also functions as a mount rack frame, without additional rigid multi-component modular support structure(s), when attached to a mount rack frame base. Each single modular rigid support structure in both the four-point frame and the second embodiment also preferably comprises structural features by which each rigid modular multi-component support structure is adjusted to compensate for mechanical deviations in (i) attaching devices that attach mounted devices to the frame (ii) as well as the mounted devices themselves. This second embodiment of the second mount rack frame may also support more than one additional rigid multi-component support structure in vertical alignment and attachment.

In a third mount rack frame there is an upper rigid horizontal component comprises a single rigid metal strip that attaches to each of two opposing rigid vertical components. There is also a lower rigid horizontal component that (i) attaches to the two opposing rigid vertical components, and (ii) weighs more than the upper rigid horizontal component. The two rigid vertical components directly oppose each other, and each rigid vertical component comprises a longitudinal vertical recess to reduce frame weight. As in the second mount rack frame, each rigid vertical component attaches to each rack base leg along the longitudinal length of the rack base leg in a perpendicular manner. Each rigid vertical component also preferably attaches to each rack base leg along the longitudinal length of each rack base leg in an anterior-posterior configuration. This anterior-posterior attachment of each rigid vertical component provides a free-standing ability to the frame even when the maximum number of stored devices are attached in vertical alignment along the longitudinal length/height of rigid vertical components.

SUMMARY OF THE INVENTION

The second mount rack frame disclosed and claimed herein comprises at least one modular rigid support structure, but this frame can contain at least four modular rigid support structures. Each modular rigid support structure contains at least two rigid interchangeable vertical components and two rigid interchangeable horizontal components, and all of which are assembled to each other within a very short time period. Each rigid horizontal component and rigid vertical component also preferably contains partially elliptical apertures and bolts or screws. These apertures congruently align for horizontal adjustment of rigid vertical components, as well as for mechanical attachment to other rigid components.

The second mount rack frame preferably contains at least two modular rigid support structures. In this preferred embodiment there is a total of four rigid vertical support components, and each modular rigid support structure is easily assembled from interchangeable rigid components. When the second mount rack frame comprises four vertical rigid components, then the second mount rack frame can support servers which range to 40 inches in depth (using 25 inch universal brackets). At least one modular rigid support structure can vertically align and stack upon another rigid modular support structure for additional device support and storage, and without additional floor space.

For all anterior and posterior modular rigid support structures, partially elliptical apertures containing bolts or screws are spaced along the rigid vertical and rigid horizontal components in aperture pairs. Several partially elliptical apertures contain a centrally positioned screw or bolt with a lateral clearance on either side of that screw of preferably and approximately 1/16 inch. As a result, certain screws within specific partially elliptical apertures can move laterally, and this lateral movement results in an adjustable horizontal distance between two opposing rigid vertical components within one modular rigid support structure. Bolts and screws within partially elliptical apertures also attach vertical rigid components to horizontal rigid components.

Other congruently aligning apertures have different functions. For example, rigid horizontal components contain smaller partially elliptical apertures for vertically attaching two modular rigid support structures to each other. Round threaded apertures within rack base legs attach rack base or straight base legs to a single rigid support structure or two module mount rack frames. Partially elliptical apertures within rigid vertical components attach (i) support plates with mechanical fasteners to stacked rigid support structures; and/or (ii) rack base legs to vertical rigid components.

Each modular rigid support structure has a horizontal length and vertical height of one ‘LT,’ or a multiple thereof. A U is the unit of measurement in the computer industry, and each U designates a horizontal width of nineteen and a perpendicular height of one and three-quarters inches (for either an attached device or the actual mount rack frame). A second U standard designates a horizontal length of twenty-four inches, but the nineteen-inch standard is more ubiquitous. Width (depth) of an attached device can vary and still remain within one U (or multiples thereof).

For example, a standard industry measurement of 3 U is equivalent to approximately 1.75×3 inches in height of the attached device (or vertical height interval along each rigid vertical component). Devices attach within each rigid support structure by vertically and linearly aligned apertures and inserted screws along rigid vertical components. There are also two sets of vertically aligned rack apertures along each rigid vertical component. As a result, the user can either attach the device more anterior or posterior along a modular rigid support structure.

In addition, each rigid vertical component end comprises apertures into which bolts or screws reversibly insert to attach a straight base leg. In the second mount rack frame, each straight base leg or rack base leg containing coasters or wheels with locking mechanisms and the same is true for the left and right rack base leg of the third mount rack frame. These coasters or wheels provide mobility to the mount rack frame or single modular rigid support structure.

Each rigid horizontal component is interchangeable structurally and functionally with all other rigid horizontal components of the same length and width. Consequently, in the second mount rack frame any rigid horizontal component can function as an upper horizontal component or a lower horizontal component of a modular rigid support structure with respect to a supporting flat surface such as a floor. Each rigid vertical component end contains partially elliptical apertures for (i) attaching a connecting plate to a two-module mount rack frame, or (ii) reversibly attaching a rack base to a rigid support structure.

To increase the storage capacity of the mount rack frame, one modular rigid support structure is stacked and aligned vertically upon the other. Since each modular rigid support structure is identical in structure and function to the other, all rigid support structures function either as the bottom or upper (stacked) modular unit. Rigid flat connecting plates, as well as additional bolts or screws, along the corresponding rigid vertical components reversibly attach an upper aligned rigid support structure upon the supporting lower modular rigid support structure.

The anterior modular rigid support structure of the four point second mount rack frame is preferably taller than the posterior rigid support structure, but they are of the same horizontal dimension. In other embodiments the posterior rigid support structure may be taller than the anterior modular rigid support structure, as anterior and posterior positions along straight base legs are reversible and interchangeable.

The anterior modular rigid support structure in combination with posterior modular rigid support structure of the second mount rack frame is designed for attachment of computer-related devices which require four point anterior/posterior attachments for adequate support. In this particular application, two anterior opposing points along opposing sides a computer related device attach to a first anterior modular rigid support structure. Simultaneously two posterior opposing points along opposing posterior sides of the same computer related device attach to the posterior modular rigid support structure.

In the preferred embodiment of the second mount rack frame, preferably both anterior and posterior rigid modular support structures are parallel to each other and attach to a first and second corresponding straight base legs to form a square or rectangle. For other embodiments, the reversibly attached first posterior modular rigid support structure is easily removed from the first anterior modular rigid support structure. When so removed, the posterior modular rigid support structure becomes the smaller lightweight and less cumbersome unit which accommodates smaller computer related devices as well as smaller budgets. None of the embodiments of this second laterally attaching frame requires attachment or support to another structure or feature that is external to the frame to be free-standing with or without attached stored devices in vertical alignment, except for contact along the bottom of the frame with a flat surface.

In the second embodiment the second mount rack frame, a single rigid multi-component modular support structure that reversibly attaches to a rack base. This rack base preferably comprises a first single straight rigid rack base leg and a second single straight rigid rack base leg. The single rigid multi-component modular support structure includes structural features by which

-   -   (i) To reversibly vertically align with and attached to at least         one additional rigid multi-component modular support structure;         and     -   (ii) To reversibly adjust a linear dimension of each rigid         multi-component modular support structure, and     -   (iii) To interchangeably attach each one of the rigid         multi-component modular support structures to the rack base so         each individual rigid multi-component support structure has         utility as a mount rack frame without vertical attachment or         alignment of other rigid multi-component support structures.

A third preferred embodiment of the mount rack frame comprises two rigid horizontal components, two rigid vertical components, a single left rack base leg and a single right rack base leg. The two rack base legs oppose and are parallel to each other with respect to each rack base leg longitudinal length. Each rack base leg longitudinal length is also quantitatively greater than the rack base leg's width or thickness. Each rack base leg has a preferred weight, and each rigid vertical component and rigid horizontal component also have a preferred weight, width, longitudinal length and thickness.

For this third embodiment the rigid upper horizontal component comprises a single metal strip that attaches to each of two opposing rigid vertical components in a perpendicular manner. The lower positioned rigid horizontal component comprises a co-extensive lower longitudinal recessed surface that includes preferably at least four, and preferably five, aligned equidistantly spaced aperture pairs. With these aligned aperture pairs and inserted mechanical fasteners, this frame can vertically align with and attach to a rigid multi-component support structure of the second mount rack frame whenever its rack base legs are omitted. In sum, this third frame exhibits some modular utility whenever a single rigid multi-component support structure with interchangeable rigid horizontal component serves as the storage unit attaching directly to a rack base.

Each longitudinal rack base leg for all disclosed embodiments comprises four apertures configured as a square for

-   -   (i) attaching a rigid vertical component along the rack base leg         in a perpendicular manner     -   (ii) with corresponding inserted mechanical fasteners, and most         preferably bolts.         Each rigid vertical component attaches to a corresponding rack         base leg at a distance from the anterior end of each rack base         leg at which (i) the mount rack frame is free-standing and (ii)         does not require support or attachment for features or devices         external to the frame (iii) except for contact along its         bottommost surfaces or coasters/wheels with a horizontal         surface.

Accordingly, it is a purpose of the present invention to provide an economical manner in which to store both heavy and lightweight computer-related devices without the use of shelves.

It is also a goal of the present invention to provide an economical manner in which to store computer-related devices mounted to a mount frame rack at two and/or four points of attachment.

It is also a goal of the present invention to provide reversibly attached modular rigid support structures for storage of vertically aligned electronic devices.

It is also a goal for the present invention to provide base legs with coasters or wheels which attach to modular rigid support structures.

It is another goal of the present invention to provide a device for adjusting a linear dimension of a modular rigid support structure.

It is another goal of the present invention to provide mechanical attachments by which a modular rigid support structure is vertically aligned upon another modular rigid support structure.

It is another goal of the present invention to provide modular rigid support structures which are structurally and functionally interchangeable with respect to vertical stacked alignment and attachment to a rack base leg or a straight base leg.

It is another goal of the present invention to provide a mount rack frame in all embodiments which is free-standing and self-balancing without attachment or support from other structural features, except for contact of a bottom rack base, coasters, or wheels with a horizontal surface

It is another goal of the present invention to provide a mount rack frame in which a single storage unit is lighter in weight and free standing whenever it supports mounted devices in vertical alignment.

It is another goal of the present invention to support vertically aligned stored devices without attachment or support to structures or features external to any embodiment of the mount rack frame.

These features, as well as other improvements of the present invention, are apparent after review of the attached figures and DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT, BEST MODE AND OTHER EMBODIMENTS.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT, BEST MODE AND OTHER EMBODIMENTS

Preferred Embodiment of Second Modular Mount Rack Frame 1

Referring initially to FIG. 1, the preferred embodiment of the second modular mount rack frame 1 comprises a first anterior modular rigid support structure 2 a and a first posterior modular rigid support structure 2 b (generally modular rigid support structures 2). Second modular mount rack frame 1 rests upon a flat horizontal surface 480 such as a floor. First anterior rigid support structure 2 a and first posterior rigid support structure 2 b preferably differ in vertical height 10 b, but have the same depth 10 c. All modular rigid support structures 2 are identical in structural features and design to each other, but with U sizes ranging from 12 through 40. The preferred embodiments and other embodiments of second modular mount rack frame 1 are free-standing. These embodiments do not require support from structures exterior to mount rack frame 1 to support vertically aligned stored devices 78 except for contact of lowermost rack base leg surfaces 606 a, 606 b or coasters and wheels 470 with a horizontal surface 480.

Referring again to FIG. 1, first anterior modular rigid support structure 2 a is preferably greater in vertical height 10 b than posterior modular rigid support structure 2 b. However, first anterior modular rigid support structure 2 a has the identical effective horizontal dimension 10 a as first posterior modular rigid support structure 2 b, and all modular rigid support structures 2 in other embodiments. Effective horizontal dimension 10 a is preferably approximately nineteen inches. Each first anterior modular rigid support structure 2 a or first posterior modular rigid support structure 2 b can support (i) mounted devices 78 and (ii) at least one additional vertically stacked rigid support structure 2 aa, 2 bb or other modular rigid support structure 2.

The discussion below addresses a first anterior modular rigid support structure 2 a within the preferred embodiment. However, the components, design and structure of first posterior and anterior modular support structures 2 a, 2 b are identical. The components, design and structure of other modular rigid support structures 2 in other embodiments is also identical to modular support structure 2 a. The vertical dimension 10 b and depth 10 c of modular rigid support structures 2 may vary in other embodiments, although (i) effective horizontal length 10 a of each modular rigid support structure 2 is always preferably approximately nineteen inches, and (ii) total horizontal length 10 p is preferably always approximately twenty-three inches.

a. Modular Rigid Support Structures 2 of Second Mount Rack Frame

Referring to FIGS. 1 and 2 of the preferred embodiment, first anterior modular rigid support structure 2 a comprises first rigid vertical component 3 a and second rigid vertical component 3 aa [generally rigid vertical components 3]. Rigid vertical components 3 a, 3 aa directly oppose each other at a 180-degree angle in an assembled rigid modular support structure 2 a, 2 b, or any other modular rigid support structures 2.

Vertical longitudinal height 10 b of each vertical rigid component 3 a, 3 aa is approximately 49 inches. Each rigid vertical component 3 a, 3 aa has an anterior vertical width side 10 d and a posterior vertical width side 10 dd of preferably approximately two inches. Each vertical rigid component 3 a, 3 b has a first and second lateral vertical side 40 d, 40 dd respectively, and each lateral vertical side has depth 10 c of approximately four and three-quarters inches. For first posterior modular rigid support structure 2 b, vertical height 10 b of each first and second vertical rigid component 3 b, 3 bb is approximately thirty-nine inches. When assembled into modular rigid support structure 2 each rigid vertical support structure is perpendicular to flat support surface 480 and horizontal components 4.

Each lateral vertical component side 40 d, 40 dd is perpendicular to, and integrally attached, to anterior or posterior rigid vertical component surfaces 10 d, 10 dd respectively. Each anterior width side 10 d and posterior width sides 10 dd comprise the same posterior side/anterior side/lateral side dimensions. Preferably each first rigid vertical component 3 a is the same vertical height as second rigid vertical component 3 aa within one assembled anterior rigid modular support structure 2 a. The same relationship is preferred for posterior vertical components 3 b, 3 bb or other embodiments. Referring to FIG. 3 of the preferred embodiment, each lateral vertical side 40 d, 40 dd contains four round penetrating apertures 601 a, 601 b, 601 c, 601 d [generically round penetrating apertures 601]. Round penetrating apertures 601 linearly and vertically align with each other along lateral vertical side 40 d or 40 dd. Referring to FIGS. 1 and 4, each rigid vertical component 3 a, 3 aa, 3 b, 3 bb comprises first and second vertical interior surfaces 35 a, 35 b respectively. Each vertical interior surface 35 a, 35 b is approximately three-quarters inch in width.

Preferably first anterior vertical rigid components 3 a, 3 aa are interchangeable with each other, while first posterior vertical rigid components 3 b, 3 bb are interchangeable with each other (assuming components 3 a, 3 aa, or 3 b, 3 bb exhibit identical width and depth). Vertical rigid components 3 a, 3 aa may not be interchangeable with components 3 b, 3 bb, if corresponding widths and depths diverge. Vertical rigid components 3 a, 3 aa, 3 b, 3 bb within their corresponding modular rigid support structures 2 a, 2 b respectively are aligned in a fixed, yet reversible mechanical manner. Each vertical rigid component 3 a, 3 aa, 3 b, 3 bb is positioned perpendicular to a flat supporting surface 480 as well as to (i) attaching straight base legs 471 a, 471 b; or (ii) attaching rack base legs 71 a, 71 b infra.

b. Rigid Horizontal Components 4 a, 4 Aa,

Referring to FIGS. 1 and 2 of the preferred embodiment of the second mount rack frame 1, first anterior modular rigid support structure 2 a also comprises first rigid horizontal component 4 a and second rigid horizontal component 4 aa. Rigid horizontal components 4 a, 4 aa are parallel to each other within assembled rigid modular support structure 2 a, 2 b, or other modular support structure 2. Rigid horizontal components 4 a, 4 aa, or those in other embodiments 4 are also parallel to the flat supporting surface 480 when assembled within rigid modular support structure 2 a, 2 b or other modular rigid support structure 2.

Referring to FIG. 1, each first and second anterior rigid horizontal component 4 a, 4 aa respectively, as well as each anterior first and second posterior rigid horizontal component 4 b, 4 bb respectively, is approximately twenty-three and five-eighths inches in total length 10 a. The effective lateral horizontal length 10 a is preferably nineteen inches, because nineteen inches is the industry standard lateral horizontal length 10 a to accommodate a single U mounted device 78. Each rigid horizontal component 4 a, 4 aa, or 4 b, 4 bb is approximately four and seven-eighths inches in horizontal width 10 f. First and second anterior rigid horizontal components 4 a, 4 aa respectively are preferably parallel to each other when assembled into modular rigid support structure 2. Similarly, first and second posterior rigid horizontal components 4 b, 4 bb respectively are parallel to each other when assembled into first posterior modular rigid support structure 2 b or in other embodiments 2. Each first and second horizontal rigid component 4 a, 4 aa, 4 b, 4 bb respectively is structurally and functionally interchangeable with the other.

Referring to FIGS. 1 and 2, at each horizontal rigid component end 19 a, 19 b is cut away section 19 c. One rigid vertical component end 15 a or 15 b inserts within a corresponding cutaway section 19 c. Each rigid horizontal component 4 a, 4 aa, 4 b, 4 bb also comprises a corresponding horizontal bottom side 13 a. Horizontal bottom side 13 a integrally and continuously attaches perpendicular to first downward side 13 b and second downward side 13 c. Each downward first and second downward side 13 b, 13 c respectively is approximately two inches in downward width 10 e.

Horizontal side 13 a and downward sides 13 b, 13 c are preferably approximately 1/16 to 3/32 inch in thickness. Rigid vertical component ends 15 a, 15 b insert and slide in a limited manner along horizontal bottommost side 13 a within corresponding cutaway section 19 c. Each rigid vertical component 3 a, 3 aa of first anterior modular rigid support structure 2 a is reversibly removable from anterior horizontal rigid components 4 a, 4 aa. Similarly, each rigid vertical component 3 b, 3 bb of first posterior modular rigid support structure 2 b is reversibly removable from posterior horizontal rigid components 4 b, 4 bb respectively. In other embodiments rigid vertical components 3 are reversibly removable from corresponding horizontal rigid components 4.

Anterior first and second rigid vertical components 3 a, 3 aa respectively are parallel to each other when assembled within first anterior modular rigid support structure 2 a. Anterior first and second rigid horizontal components 4 a, 4 aa respectively are parallel to each other and attach at a right angle to vertical rigid components 3 a, 3 aa respectively when assembled as first modular rigid support structure 2 a. Components 3 a, 3 aa, 4 a, 4 aa thereby preferably form a rectangle or square within one plane, as do components 3 b, 3 bb, 4 b, 4 bb in a posterior rigid modular support structure 2 b, or other embodiment of rigid modular support structures 2 with components 3, 4. However, other four-sided polygons and other two-dimensional or three-dimensional shapes are also within the scope of the invention.

c. Partially Elliptical Apertures 17,17 a

Referring to FIG. 5C, each rigid vertical component 3 a, 3 aa, or 3 b, 3 bb contains vertically aligned aperture pairs 14 aa, 14 bb, 14 cc, 14 dd (generically vertical pairs 14 h) of large partially elliptical apertures 17. Vertical aperture pairs 14 h are located within first and second vertical components end 15 a, 15 b along vertical sides 10 d, and 10 dd. As best seen in FIG. 8A, in the preferred embodiment each large partially elliptical aperture 17 within aperture pairs 14 h has an aperture longitudinal axis 14 e perpendicular to vertical height 10 b of corresponding rigid vertical component 3 a, 3 b. Each large partially elliptical aperture 17 comprises midpoint 14 c along aperture longitudinal axis length 14 e. Each large partially elliptical aperture 17 within vertical pair 14 h is preferably approximately (i) seven-sixteenths inch in aperture longitudinal axis length 14 e and (ii) one-quarter inch in aperture height 14 n. However, other aperture shapes and dimensions are also within the scope of the invention.

Each large partially elliptical aperture 17 provides a lateral clearance of 1/16 inch on each side of an inserted bolt 50 x. Each large partial elliptical aperture 17 is designed to reversibly receive one threaded bolt 50 x. Threaded bolt 50 x preferably has a maximum hexagonal head dimension of five-eighths inch, a threaded stem with mated hex nut (not seen) and a washer (not seen). Threaded stem is approximately one-quarter inch in diameter and three-quarters inch in length. There is a maximum lateral clearance of approximately 1/16-inch on each side of a centrally positioned threaded bolt 50 x along aperture long axis 14 e. There is also a maximum lateral clearance of approximately 1/16 inch on each side of a centrally positioned large round threaded screw 50 a within smaller partially elliptical aperture 17 a, or in other embodiments. Preferably large round threaded screw 50 a has a diameter of approximately one-half inch and a stem diameter of approximately three-sixteenths inch and includes a circular washer (not seen).

Vertical aperture pairs 14 h (4 aa, 14 bb, 14 cc, 14 dd) are positioned at rigid vertical component ends 15 a, 15 b within corresponding first and second rigid vertical component anterior and posterior vertical sides 10 c, 10 d respectively. Two partially elliptical apertures 17 within each pair 14 h align directly above or below each other within corresponding anterior vertical side 10 d or posterior vertical side 10 dd. Still referring to FIG. 5C, each rigid horizontal component 4 a, 4 aa, 4 b, 4 bb, or other rigid horizontal components 4 in other embodiments, comprises first, second, third and fourth horizontal aperture pairs 14 a, 14 b, 14 c, 14 d respectively (generically horizontal aperture pairs 14). Each horizontal aperture pair 14 is located at first and second horizontal component ends 19 a, 19 b respectively, within first and second horizontal downward sides 13 b and 13 c respectively. Each horizontal aperture pair 14 comprises two large partially elliptical apertures 17.

Each large partially elliptical aperture 17 within a horizontal pair 14 a, 14 b, 14 c, 14 d (generically horizontal pairs 14) is identical in shape and dimension to large partially elliptical apertures 17 within vertical pairs 14 h. Each aperture long axis 14 e within aperture pairs 14 is parallel to the effective longitudinal length 10 a of its corresponding rigid horizontal component 4. Within an assembled modular rigid support structure 2 a, 2 b or other structures 2, each horizontal aperture pair 14 congruently aligns with corresponding vertical aperture pair 14 h, i.e.: 14 a, 14 aa, 14 b, 14 bb, etc.

Still referring to FIG. 5C, in the preferred embodiment first, second, third, fourth and fifth horizontal pairs 16 a, 16 b, 16 c, 16 d, and 16 e respectively (generically laterally aligned pairs 16) of smaller partially elliptical apertures 17 a penetrate horizontal central side 13 a. Each smaller partially elliptical aperture 17 a is identical in design and shape to large partially elliptical aperture 17, so that each smaller partially elliptical aperture 17 a has an aperture midpoint 14 c and an aperture height 14 n (not seen). Each large partially elliptical aperture 17 also has an aperture longitudinal axis 14 e (not seen) perpendicular to longitudinal vertical height 10 b of corresponding rigid vertical component 3 a, 3 b or 3.

Horizontally aligned pairs 16 are equidistantly spaced from each other and are parallel to each other. Other numbers of laterally aligned pairs 16 containing smaller partially elliptical apertures 17 a are also within the scope of the invention. In other embodiments of the second mount rack frame horizontally aligned pairs 16 and apertures 17 a comprise diverse shapes and dimensions, as well as other linear distances between each adjacent apertures or aperture pairs.

Still referring to FIG. 1, each first and second stamped metal strip 36 a, 36 b respectively also comprises a first or second exterior edge 36 aa, 36 bb respectively. Preferably stamped metal strips 36 a, 36 b are identical in design and structure. Preferably, stamped metal strips 36 a, 36 b are also interchangeable with respect to attachment to rigid vertical component 3 a and 3 aa, 3 b, 3 bb or 3 whenever rigid vertical components 3 are the same longitudinal vertical height 10 b. However, vertical height, width and thickness of stamped metal strips 36 in other embodiments may differ. Referring to FIG. 5C, each stamped pair 37 a is parallel to and aligned with its opposing stamped pair 37 b along its opposing rigid vertical component 3 a, 3 aa or 3 b, 3 bb within an assembled first anterior or first posterior modular rigid support structures 2 a, 2 b. Stamped metal strips 36 a, 36 b are also parallel to longitudinal length 10 b of corresponding rigid vertical component 3 a, 3 aa or 3 b, 3 bb to which stamped metal strip 36 a, 36 b attaches.

e. Mounted Device 78 Attachment Structures

Mounted devices 78 mounted and stored upon second modular mount rack frame 1 are generally, but not exclusively, computer-related and include, although not exclusively: servers, hubs, switches and routers. Similarly to modular rigid support structures 2, mounted devices 78 are categorized within internationally designated U units. Mounted device 78 of one U unit is approximately (i) nineteen inches in anterior length and (ii) one and three-quarter inches in vertical height, although depth may vary. Because the international standard height U is 1 and ¾ inches, most manufacturers design their devices 78 and attaching brackets 75 accordingly. Each one U device 78 is approximately 1 and 11/16 inches in height. Consequently, when devices 78 are mounted upon a modular rigid support structure(s) 2, there is approximately 1/32 inch of vertical space between vertically aligned adjacent devices 78 within a modular rigid support structure 2.

As best seen in FIGS. 2 and 4, smaller lighter computer-related mounted devices 78 i only require two anterior mechanical attachments to stamped metal strips 36 a, 36 b of two opposing rigid vertical components 3 a, 3 aa or 3 b, 3 bb. Opposing two anterior mechanical attachments are sufficient to support the weight of a hub, switch or router 78 i. Referring to FIG. 6, larger computer related devices 78 t such as servers require: (i) two opposing points along each anterior device segment 555 of each opposing device side 78 a, 78 b respectively; and (ii) two opposing points along each first and second posterior segment portion 556 of each opposing device side 78 a, 78 b respectively.

In another embodiment, computer related devices 78 i mount to a sole and only rigid modular support structure 2 within second modular mount rack frame 1. This embodiment requires that one modular rigid support structure 2 a, 2 b, or other modular rigid support structure 2, attach solely and exclusively to first and second rack base legs 7 a, 71 b. Also in this embodiment, there can only be two anterior attachments at anterior opposing segments 555 of a smaller computer related device 78 i.

Referring to FIG. 6, prior art mounting bracket 75 reversibly attaches to mounted device 78 i by countersink or bevel head screws 50 g. Screws 50 g are preferred because they fit flush along a bracket surface. However, other prior art mounting brackets 75, screws and mechanical attachments are satisfactory in other embodiments. Both anterior device side segments 555 of opposing device sides 78 a, 78 b extend posterior from anterior device edge 557 in an anterior-posterior dimension 78 f. First, second and third mounting aperture pairs 53 a, 53 b, 53 c (generically mounting aperture pairs 53) each comprise vertically aligned mounting round apertures 51 a. Each mounting aperture pair 53 linearly aligns with remaining pairs 53 along each opposing first and second device sides 78 a, 78 b (not seen in this view) in anterior/posterior direction 78 f. Each mounting aperture pair 53 aligns parallel to posterior device edge 557. Each mounting aperture pair 53 reversibly receives one countersink or bevel head screw 50 g within each mounting pair's corresponding mounting round aperture 51 a.

There is approximately one to five inches between anterior mounting aperture pairs 53 a, 53 b and one to five inches between mounting aperture pairs 53 b and 53 c. Mounting pair 53 a is approximately one to five inches from anterior edge 557, while mounting aperture pair 53 c is approximately one to five inches from posterior device edge. Still referring to FIG. 6, in the preferred embodiment each prior art mounting bracket 75 preferably comprises flat bracket end 75 a, bracket flat segment 75 d, and bent bracket end 75 b. Flat bracket segment 75 d comprises flat end apertures 75 c, and each flat end aperture 75 c can congruently align with a corresponding mounting round aperture 51 a. Bent bracket end 75 b is integrally part of, but perpendicular to bracket flat segment 75 d. Bent bracket end 75 b comprises bent bracket apertures 75 e, through which preferably large round Phillips head or straight head screw 50 k insert.

Prior art cage nut 59 comprises first and second opposing crimped flanges 59 a, 59 b, a square configuration and centrally positioned threaded round cage aperture 59 c. Cage nut 59 is approximately ⅜ inch in length upon on each side. Cage nut 59 inserts within a single rack aperture 8 and is held therein by opposing protruding first and second cage flanges 59 a, 59 b respectively. One round threaded screw 50 b inserts within each threaded round cage aperture 59 c and congruently aligned bent rack apertures 75 e, thereby connecting attaching stamped metal strip 36 a or 36 b to bent bracket end 75 b.

To attach mounted device 75 i at two anterior points to mounting bracket 75, one counter-sink or beveled head small round screw 50 g inserts through

(i) each of two mounting round apertures 51 a of a pre-selected mounting aperture pair 53 a or 53 b to congruently align with;

(ii) each of one of two flat end apertures 75 c;

(iii) for a total of two counter sink or beveled round head screws 50 g attaching mounted device 78 to mounting bracket 75 (mounting bracket 75 in turn being connected to stamped metal strip 36 a, 36 b by bent bracket end 75 b, screws 50 k and cage nuts 59). FIGS. 4 and 6.

For the above described two-point attachment, one anterior aperture pair 53 a or 53 b is selected, with that aperture pair 53 a, 53 b being the same opposing aperture pair on each opposing device side 78 a, 78 b. With four-point attachment, opposing anterior two point attachment is identical, with addition to two point attachments at aperture pair 53 c. For posterior attachment at posterior aperture pairs 53 c, brackets 75 and cage nuts 59 attach to device 78 and stamped metal strip 36 a, 36 b in a manner identical to two-point attachment of anterior aperture pairs 53 a or 53 b. Please see FIGS. 2 and 6.

Each rigid flat connecting plate 90 preferably comprises large partially elliptical plate apertures 92 a, 92 b, 92 c, 92 d, 92 e, 92 f, 92 g and 92 h (generically plate apertures 92). Plate apertures 92 form two linearly aligned sets of four apertures 92 at each adjacent first and second opposing plate edges 93 a, 93 b respectively: 92 a, 92 b, 92 c, 92 d respectively; and 92 e, 92 f, 92 g, 92 h respectively. However, other numbers and positions of plate apertures 92 are also satisfactory. Preferably each plate aperture 92, as measured from each plate aperture center 92 j, lies approximately five-eighths inch from the first or second corresponding longitudinal opposing plate edge 93 a or 93 b. Interior positioned plate apertures 92 b, 92 c are one and one-quarter inch apart from each other, as are interiorly positioned plate apertures 92 f, 92 g. Distal positioned plate apertures 92 a, 92 d and 92 e, 92 h are one and three-quarters inches from each other. Each plate aperture 92 is preferably identical to large partially elliptical aperture 17 in dimensions and shape.

Still referring to FIG. 5B, plate apertures 92 congruently align with corresponding horizontally aligned large partially elliptical apertures 17 within two square sets 18 of a lateral vertical component side 40 d or 40 dd. Congruently aligned large partially elliptical apertures 17 and plate apertures 92 thereby mechanically attach two adjoining rigid vertical components 3 a, 3 aa, 3 b, 3 bb, or other components 3 with bolts 50 x, to form a stable continuous vertical structure. Also as seen in FIG. 5B, horizontal aperture pairs 16 within upper positioned rigid horizontal component 4 aa to congruently align with their spatial counterparts within lower rigid horizontal component 4 a. One screw 50 a inserts though each of congruently aligned horizontal aperture pairs 16 a, 16 b, 16 c, 16 d, and 16 e within both rigid horizontal components 4 a, 4 aa to mechanically attach two vertically aligned modular rigid support structures 2 to each other. Each flat connecting plate 90 structurally attaches to interchangeably attaching vertically aligned rigid vertical component ends 15 a,15 b of rigid vertical components 3 a, 3 b as described supra for embodiments of second mount rack frame 1.

Referring to FIG. 7, a fourth embodiment of second mount rack frame 1 comprises first anterior modular rigid support structure 2 a and upper vertically positioned second anterior modular rigid support structure 2 aa. Attachment of flat rigid connecting plates 90 a, 90 b is identical in third and fourth embodiments, as well as in other embodiments. Attachment by congruently aligned horizontal aperture pairs 16 and screws 50 of connecting plates 90 a 90 b is identical to that described supra for other embodiments of the second modular mount rack frame.

Best Mode and Preferred Assembly of One Modular Rigid Multi-Component Support Structure 2 for Second Modular Mount Rack Frame 1

In the best mode, the assembly of modular rigid support structures 2 a, 2 aa, 2 b and 2 bb is identical for other modular rigid support structures 2. For illustration purposes the following example primarily describes assembly of first anterior modular rigid support structure 2 a. Referring to FIG. 5C, the operator initially selects a first rigid vertical component 3 a and a first rigid horizontal component 4 a. He or she next inserts one vertical component end 15 a of first rigid vertical component 3 a within corresponding cut-out segment 19 c of first rigid horizontal component 4 a. He or she then inserts one threaded bolt 50 x through each of two congruently aligned horizontal large partially elliptical apertures 17 within each aperture pair 14 aa/14 a and 14 b/14 bb. This procedure results in the attachment of one rigid vertical component end 15 a to one rigid horizontal component end 19 a at location A.

The operator next inserts one end 15 a of second rigid vertical component 3 aa within corresponding cutout 19 c of second horizontal component end 19 b of first rigid horizontal component 4 a. He or she congruently aligns each of two large partially elliptical apertures 17 of aperture pairs 14 a/14 aa and 14 b/14 bb in an identical manner to that described immediately supra. The operator inserts and tightens one threaded bolt 50 x through each two congruently aligned large partially elliptical apertures 17 of horizontal and vertical aperture pair's 14 a/14 aa and 14 b/14 bb. This procedure attaches one vertical component end 15 a to one horizontal component end 19 b at location B.

The operator next inserts second vertical component end 15 b within corresponding cutout segment 19 c at rigid horizontal end 19 b of second rigid horizontal component 4 aa. He or she congruently aligns aperture pairs 14 c/14 cc and 14 d/14 dd as described previously for aperture pairs 14 a/14 aa and 14 b/14 bb. Threaded bolts 50 x insert through aligned aperture pairs 14 c/14 cc, 14 d/14 dd to attach rigid vertical component 3 aa to second rigid horizontal component 4 aa at location C.

At location D, vertical aperture pairs 14 cc, 14 dd at vertical end 15 b of rigid vertical component 3 a congruently align with horizontal aperture pairs 14 c, 14 d respectively at horizontal end 19 a of second rigid horizontal component 4 aa. Threaded bolts 50 x insert through aligned pairs 14 c/14 cc and 14 d/14 dd as previously described. Preferably all rigid vertical component ends 15 a, 15 b are identical to each other, and all rigid horizontal component ends 19 a, 19 b are identical to each other. In other modes rigid horizontal components 4 a, 4 aa and rigid vertical components 3 a, 3 aa interchangeably and reversibly assemble in a different chronological order.

Still referring to FIG. 5C, after assembly of one modular rigid support structure 2 a, there are a total of sixteen large partially elliptical apertures 17: (i) eight large partially elliptical apertures 17 in an anterior orientation; and (ii) eight partially elliptical apertures 17 in a posterior orientation. In other embodiments rigid vertical components 3 and rigid horizontal components 4 assemble into other four-sided polygons, or other shapes, to form modular rigid support structure 2.

Assembly of the Preferred Embodiment of Second Mount Rack Frame 1

a. Best Mode of Attaching Modular Rigid Support Structures 2 a, 2 b to First and Second Straight Base Legs 471 a, 471 b

Referring to FIGS. 3 and 5B, the operator initially selects one straight base leg 471 a or 471 b for attachment to rigid vertical component 3 a or 3 aa of completely assembled first anterior modular rigid support structures 2 a. He or she congruently initially aligns (i) square aperture set 18 b with (ii) corresponding square aperture set 400 k within corresponding straight leg upwardly protruding wall 400 j.

The operator inserts and tightens single threaded bolt 50 x through each pair of congruently aligned large partially elliptical apertures 17 within (i) corresponding straight leg upwardly protruding wall 400 j and (ii) square aperture set 18 b within vertical lateral component side 40 dd.

The operator follows the same procedure for attachment of rigid vertical component 3 aa, 3 b, 3 bb or other rigid vertical component 3 to straight base leg 471 a, 471 b. This procedure includes insertion of bolts 50 x through remaining three straight leg exterior square sets 400 k and corresponding congruently aligned partial elliptical apertures 17 of remaining three aperture square sets 18.

After complete assembly of the preferred second modular mount rack frame 1, each straight base leg 471 a, 471 b is (i) parallel to the other. Each straight base leg 471 a, 471 b is also perpendicular to corresponding attached rigid vertical components 3. However, other attachment chronologies and procedures also exist within the scope of the invention.

(2) Attachment of Rigid Horizontal Components 4 to Straight Base Legs 471 a, 471 b

As best seen in FIG. 5B, each horizontal component end 19 a, 19 b attaches to a corresponding inner longitudinal leg ledge 400 f. The operator congruently aligns (i) smaller partially elliptical apertures 17 a within an outermost horizontal pair 16 a, 16 e within rigid horizontal component 4 a, 4 a, 4 b, 4 bb, or 4; with (ii) two threaded round apertures 17 b within one corresponding inner longitudinal leg ledge 400 ff.

The operator then inserts and tightens large one round threaded screw 50 a through each congruently aligned smaller partially elliptical aperture 17 a within horizontal pair 16 a or 16 e, and corresponding threaded round aperture 17 b. The operator repeats this procedure for remaining congruently aligned outermost horizontal aperture pairs 16 and threaded round apertures 17 b of inner longitudinal leg ledge 400 f.

Each anterior surface 10 d of rigid vertical component end 15 a is positioned three inches from corresponding anterior straight base leg end 400 h when corresponding anterior rigid vertical component 3 a, 3 aa is properly attached to straight base leg 471 a, 471 b. Each posterior vertical surface 10 dd of rigid vertical component end 15 a of posterior rigid vertical component 3 b, 3 bb is flush with corresponding posterior straight base leg end 400 hh.

Best Mode Attachment of Modular Rigid Support Structure 2 to Rack Base Legs 71 a, 71 b in the Second Embodiment of Second Modular Mount Rack Frame 1

Referring to FIG. 5A, each first and second rigid vertical component 3 a, 3 aa, 3 b, 3 bb, or 3 respectively attaches approximately six inches posterior to each corresponding first and second anterior rack base leg end 71 aa, 71 bb respectively. First, second, third and fourth partially large elliptical leg apertures 81 a, 81 b, 81 c, 81 d (generically rack large partially elliptical leg apertures 81) within each upwardly slanting rack leg wall 73 d, respectively congruently align with square aperture pairs 18 of a corresponding vertical component end 15 a.

Each two congruently aligned apertures 81/18 mechanically connects to each other by insertion of single threaded bolt 50 x. In embodiments comprising a single modular rigid support structure 2 with rack base legs 71 a, 71 b, these bolts 50 x provide attachment of rigid vertical components 3 to rack base legs 71 a, 71 b.

Horizontal rigid components 4 attach to rack base legs 71 a, 71 b, by horizontal aperture pairs 16 a or 16 e and corresponding ledge apertures 778 a, 778 b. Apertures 778 a, 778 b congruently align with small partially elliptical apertures 17 a with aperture pair 16 a or 16 e. The operator then inserts and tightens one large screw 50 a through apertures 778 a/16 a, 778 b/16 a, or 778 a/16 e, 778 b/16 e.

Referring to FIGS. 2, 3 and 5B, prior art coasters or wheels 470 attach to lowest straight leg surface 400 p at each anterior straight base leg end 400 h or posterior base leg end 400 hh. Prior art coasters or wheels 470 attach with well-known prior art devices 481 by four small round screws 50 g to lowest straight leg surface 400 p in a pivoting manner. Referring to FIG. 5A, rack coasters 70 attach to each rack base leg 71 a, 71 b at rack base ends 71 in a pivoting manner. Rack coasters or wheels 70 attach to base legs 71 a, 71 b by pivoting conventional prior art attachments 51 b and mechanical fasteners 50 b in a manner similar to that of straight base legs 471 a, 471 b described supra. However, other chronologies and procedures for frame assembly are also within the scope of the invention.

Best Mode of Assembly of Second Modular Mount Rack Frame 1 for Vertically Aligned and Attaching Uppermost Modular Rigid Support Structure 2 b in the Preferred Embodiment and Second Embodiment

Referring to FIG. 5B, to attach one uppermost modular rigid support structure 2 bb, the operator positions second posterior modular rigid support structure 2 bb upon upper first rigid horizontal component 4 aa of lower positioned first posterior modular rigid support structure 2 b. Horizontal aperture pairs 16 within lower rigid horizontal component 4 a of second posterior modular rigid support structure 2 bb are now congruent with aperture pairs 16 within upper first rigid horizontal component 4 aa of first posterior modular rigid support structure 2 b. The operator inserts and tightens one large round threaded screw 50 a through each pair of smaller partially elliptical aperture 17 a/17 a within each congruently aligned horizontal aperture pair 16 of adjoining rigid first and second horizontal components 4 a, 4 aa.

The operator next congruently aligns plate apertures 92 of flat rigid connector plates 90 a with

(i) corresponding vertical aperture sets 18 a/18 c along

(ii) lateral vertical component sides 40 d of rigid vertical components ends 15 a, 15 b of rigid vertical support components 3 bb, 3 bb

(iii) of first posterior modular rigid support structure 2 b and upper second posterior modular rigid support structure 2 bb.

The operator then inserts and tightens bolt 50 x through each of the eight pairs of congruently aligned apertures 17/92. The operator repeats this identical procedure with second flat rigid connector plate 90 b along rigid vertical component ends 15 a, 15 b of remaining rigid vertical components 3 bb, and 3 bb.

This identical procedure as described immediately supra, with rigid horizontal aperture pairs 16 and flat rigid connector plates 90, is also the best mode for upper vertical attachment of first anterior modular rigid support structure 2 a to second anterior modular rigid support structure 2 aa in another embodiment. Rigid horizontal components 4 a, 4 aa are preferably identical in structure and dimensions, so horizontal rigid components 4 a, 4 aa are reversible with respect to upper and lower vertical positions.

With respect to horizontal aperture pairs 16, the same attachment procedure with screws 50 a remains the best mode for the preferred embodiment, as illustrated in FIG. 1. Preferably connector plates 90 are included within the best mode for upper vertical attachment of any modular rigid support structure 2 to another modular rigid support structure 2 in other embodiments.

Best Mode of Attaching Mounted Device 78 to the Preferred Embodiment of Second Modular Mount Rack Frame 1 and Other Embodiments

a. Anterior Two Opposing Point Attachment

(1) Connecting Device 78 to Bracket 75

Referring to FIGS. 4 and 6, the operator congruently aligns mounting bracket 75 to first opposing device aperture pair 53 a and 53 b. He or she inserts and tightens single screw 50 g through each corresponding congruently aligned device aperture 51 a and bracket aperture 75 c.

(2) connecting bracket 75 to stamped metal strip 36 a, 36 b

The operator inserts two cage nuts 59 within two vertically adjacent corresponding rack apertures 8 of first or second stamped metal strip 36 a, 36 b. The operator inserts each cage nut 59, so each first and second cage nut flange 59 a, 59 b respectively protrudes anterior from each corresponding rack aperture 8.

The operator orients mounting bracket 75 so two bent bracket apertures 75 e congruently align with corresponding cage nut apertures 59 c within respective rack apertures 8. The operator next inserts and tightens Philips screw 50 k through each corresponding congruently aligned rack apertures 8, bent segment aperture 75 e, and cage nut aperture 59 c. During this step the operator inserts Phillips screw 50 k into cage nut aperture 59 c through protruding cage nut flanges 59 a, 59 b.

The operator repeats this identical process on the second opposing device side 78 b (not seen in FIG. 6), and thereby attaches second opposing side 78 b to corresponding stamped metal strip 36 a or 36 b. The operator can orient mounting bracket bent end 75 b for attachment through rack apertures 8 of posterior stamped metal strip 36 b or anterior stamped metal strip 36 a. To disengage mounted device 78, the operator removes each Phillips screw 50 k from congruently aligned cage nut 59, rack aperture 8 and bent racket aperture 75 e.

This prior art attachment as described for rigid vertical component 3 a is the best mode for all other modular rigid support structures 2 and devices 78 i. Other numbers of prior art bent bracket apertures 75 e, with corresponding rack apertures 8 and prior art cage nuts 59, are also within the scope of the invention. In some embodiments mounting options also depend upon the design features of the manufacturer.

b. Four Opposing Point Attachment

Referring to FIGS. 2 and 6, the mechanics of attachment are identical to those for two point opposing point attachment with respect to anterior aperture pairs 53 a and/or 53 b. However, on each posterior opposing side segment 556, cage nut flanges 59 a, 59 c protrude posterior where device 78 attaches at opposing posterior device aperture pairs 53 c, and so bent bracket end 75 b also faces posterior.

Consequently mounted device 78, such as computer server 78 t, attaches at

-   -   (i) First or second anterior device aperture pairs 53 a or 53 b         respectively along the device's first and second opposing sides         78 a, 78 b respectively; and     -   (ii) Posterior device aperture pair 53 c along the same device's         first and second opposing sides 78 a, 78 b respectively,         for a total of eight attachment points.

Referring to FIG. 6, in the best mode each device aperture pair 53 a, 53 b, 53 c and corresponding cage nuts 59 are positioned the same vertical distance along corresponding stamped metal strips 36 a or 36 b from flat supporting surface 480 when supporting single device 78 t. In embodiments with at least two opposing modular rigid support structures 2, there is sufficient structure for solely anterior support (two-point attachment) or anterior-posterior support (four-point attachment).

For example, smaller mounted devices 78 i can be supported at device anterior segment 555 with two-point attachment by any modular rigid support structure 2, such as modular rigid support structures 2 a, 2 aa, 2 b, 2 bb. Similarly, larger mounted devices 78 t can be supported at device posterior 556 by any modular rigid support structures 2 for four-point attachment. As seen in FIG. 4, in other embodiments, a sole and single modular rigid support structure 2 provides anterior two-point attachment.

Modification of a Linear Dimension 10 a Between Rigid Vertical Components 3 within Each Rigid Multi-Component Support Structure 2, 2 a and 2 b in the Second Modular Mount Rack Frame in the Preferred Embodiment, Second Embodiment and Other Embodiments

In the pending invention there is one U unit of vertical height (i. e., one and three-quarter inches) for each subset 7 of three rack apertures 8. Referring now to FIGS. 8A and 8B, many mounted devices 78 deviate from the U industry standard of nineteen inches of horizontal length 10 a. In addition, prior art brackets 75 often exhibit variations in thickness of bent segment 75 b and flat segment 75 d. These variations may interfere with precise fittings between rack apertures 8 and mounted device opposing sides 78 a, 78 b.

As seen in FIGS. 8a and 8B, the operator can adjust the effective horizontal length 10 a between for example, two opposing rigid vertical components 3 a, 3 aa, or 3 b, 3 bb within a single modular rigid support structure 2 a, 2 b, 2 bb. This same procedure is applicable to any other pair of opposing rigid vertical components 3 within single modular rigid support structure 2.

To adjust effective horizontal length 10 a, the operator initially loosens each bolt 50 x and connected hex nut (not seen) within congruently aligned vertical aperture pairs 14 and 14 h within a single or two opposing rigid vertical components 3 a, 3 aa, 3 b, 3 bb or 3. The operator loosens Phillips screw 50 a from each exterior positioned horizontal aperture pair 16 a or 16 e which congruently aligns with round threaded apertures 402 a, 402 b within corresponding attached straight base leg interior ledges 471 ff.

Referring to FIG. 8A, preferably there is longitudinal clearance of approximately one-sixteenth inch on each side of each originally inserted bolt 50 x or screw 50 a. This clearance limits the distance each bolt 50 x or large round screw 50 a may move laterally to increase effective distance 10 a. The operator loosens bolts 50 x and mated hex nuts inserted within each pair of (i) partially elliptical apertures 17 of aperture set 400 k or 400 kk; and (ii) partially elliptical apertures 17 of corresponding square aperture sets 18. As best seen in FIG. 8B, the operator manually moves each rigid vertical component 3 a/3 aa, 3 b/3 bb, or 3/3 (depending upon the embodiment) laterally in an exterior direction within corresponding cutout segment(s) 19 c. This lateral movement continues until each bolt 50 x or large round screw 50 a abuts outermost edge 14 g of corresponding partially elliptical aperture 17 or 17 a. The operator then tightens bolts 50 x within lateral vertical aperture sets 18 and square aperture sets 400 k and/or 400 kk, as well as partially elliptical aperture pairs 14, 14 h and 16.

To decrease effective horizontal length 10 a the operator manually moves each rigid vertical component 3 a, 3 aa or 3 b, 3 bb (or both depending upon the embodiment) laterally inward within each cutout segment section 19 c, and until each bolt 50 x abuts innermost partially elliptical aperture edge 14 f of corresponding partially elliptical apertures 17, 17 a. For both inward and outward lateral adjustments, after positioning rigid vertical components such as 3 a, 3 aa, the operator tightens bolts 50 x, hex nuts and Phillips screws 50 a.

The same procedure for lateral adjustment applies to embodiments which (i) comprise vertically positioned rigid modular support structures such as 2 aa or 2 bb. In these embodiments vertically aligned modular rigid support structures 2 can be laterally adjusted together, or independently of one another. The same procedure for lateral adjustment also applies to embodiments of second modular mount rack frame 1 with sole and single rigid modular support structure 2.

Referring to FIG. 16, prior art power strip 600 reversibly attaches to one rigid vertical component 3 with small round screw 50 as (not seen in this view) at each aperture 744 a, 744 b within each vertical component lateral side 608 g as described supra for second mount rack frame 1.

Each vertical component side 608 g, 608 h, 608 i is preferably (i) rigid and (ii) integrally continuous with at least one remaining vertical component side 608 g, 608 h and 608 i.
